The Sudbury Water District is an independent municipal entity established by an Act of the Massachusetts Legislature in 1934. It is separate and distinct from the Town of Sudbury, and is not affiliated with the Town of Sudbury’s Department of Public Works.

As provided for in the Federal Safe Drinking Water Act (SWDA) (P.L. 93-523) enacted 1974 and as amended, and the Commonwealth of Massachusetts Drinking Water Regulation, 310 CMR 22.22, Sudbury Water District acting as a public drinking water supplier, has undertaken the primary responsibility for preventing water from unapproved sources, or any other substances, from entering the public potable water supply:

In compliance with these regulations, Sudbury Water District has contracted a Massachusetts certified cross connection surveyor to inspect and test commercial, industrial and institutional facilities connected to public water.

Pursuant to Massachusetts Drinking Water Regulations, 310 CMR 22.22 (13)(b) in the event a backflow prevention device fails testing, as determined by the District or its agent, repair or replacement by a Massachusetts licensed plumber or in the case of fire protection a Massachusetts licensed fire sprinkler fitter / contractor must occur within 14 days of the initial inspection performed; within the same (14) calendar period the owner shall contact the Sudbury Water District directly by telephoning (978) 443-6602 to schedule re-testing of the repaired/replaced device.

A $60.00 fee is assessed upon each test and retest; refusal to observe backflow-testing and inspection may result in loss of water until corrective action is taken.
